COMPARISON OF C3, C4, AND CAM PLANTS C3 C4 CAM Found in most plants Found in tropical grasses such as corn, sugarcane Specially in succulents growing under semi arid condition. e.g ; pineapple, agave Fixed carbon in Calvin cycle – attach CO 2 to RuBP Fix carbon in cytoplasm – attach CO 2 to PEP Fix carbon at night only, fix it to organic molecules With high temperature, photorespiration predominates in C3 plants With high temperature, Calvin cycle predominates C4 plants With high temperature, Calvin cycle predominates C4 plants First stable product 3PGA First stable product OAA (Oxalo acetic acid) First stable product OAA (Oxalo acetic acid) Enzyme- Rubisco Enzyme- PEP-ase Enzyme -PEP-ase Most energy efficient method Half way between these two Best water conservation Loses water through photorespiration Loses water Loses least water Bundle sheath cell lacking chloroplast Bundle sheath cell having chloroplast Large vacuoles in mesophyll cell
